Prior to the acquisition, Frontline was an equity investee. Orbotech acquired all of the joint venture interests it did not previously own for $85.0 million in cash on hand and agreed to pay an additional $10.0 million in cash over four years plus a cash earn-out of not less than $5.0 million and up to $20.0 million. The earn out amounts are based on revenues from a Frontline product currently under development.

As of December 31, 2019, the estimated fair market values of the four-year cash payment and the earn-out were $6.5 million and $3.1 million, respectively, and these amounts have been included in current and non-current liabilities at $2.3 million and $7.3 million respectively.
